BUTTON OR STUD.

SPECIFICATION forming part 0f Letters :Patent No. 653,655, datedd'uly 1'7, 1900. Application filed April 1'7, 1900.l Serial No. 13,231. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, J AMES CAMPBELL, a citiabutton or stud securely in a buttonhole or.

eyelet in a shirt-front.

My invention relates to that type of studs which are primarily intended for use with eyelet-holes in shirt-bosoms, but which may be used for ordinary buttonholes provided the sliding bar is made of suiflcient length at the` opposite sides of the stem to retain the button in place. A stud of this type, known in the art as the pipe-stem7 stud, consists of a hollow stem containing a spiral spring and a pin or shank against which the spring bears to push it out of the stem to form a cross-bar to prevent the button from falling out of the eyelet-hole. This stud works fairly well for eyelet-holes, but for ordinary buttonholes is inefficient, because the spring must be so long to project the pin sufficiently far and the convolutions of the spring must be so far apart or open that its strength is not sufficient to perform its function well.

Myinvention involves quite a dierent construction and enables me to use a sliding tube or bar of any length desired and to dispense with the objectionable spring.

The objects and advantages referred to are attained by means of the construction illustrated in the accompanying drawings, which form part of this specification, and in which- Figure 1 is a side view of a stud made in accordance with my invention. Fig. 2 is a partial longitudinal section of the same. Fig. 3 is a section of thev hollow stem with a head secured thereto. Fig. 4 is a longitudinal section of the sliding tube. Fig. 5 is a side view of a pin which I may use in the construction of my stud. Fig. 6 is a longitudinal sectionA parts wherever they occur in the different views of the drawings.

As shown in Figs. 1, 2, and 3, my stud consists of a suitable head 1, a post 2, extending centrally from the back thereof, and a hollow stem 3, bent at right angles to the post. The outer Wall of the bend in the post is provided with an aperture 4, which forms an opening for the insertion of the sliding bar or tube 5. This sliding bar or tube may be constructed in various ways, and as shown in Figs. 1, 2, and 3 consists of a tube the outer ends 6 ot' `which are intact and the central portion 7 is cut away upon opposite sides to forni two spring members 8. These members are bent to form a swell or enlargement designed to engage the walls of the aperture 4 and hold said sliding bar or tube in the position shown in Figs. 1 and 2. To give a finished appearance to the sliding bar or tube and to facilitatethe entrance into eyelet or buttonhole, I secure in one end of the tube the pin 10, having head 11, or I may use a pin like that shown in Fig. 5 in either the hollow stem or the sliding tube to stiften and strengthen it.

As shown in Fig. 6, the sliding stem is provided with a central aperture 12 and a bowed spring 12a, fitted into the aperture to engage the aperture 4.

Fig. 7 shows a construction in which a wire spring 12b is seated in an aperture in the tube.

Fig. 8 shows a tube slitted to form a bulging spring 13, and Fig. 9 shows a tube at one 'end and a pin 14 at the opposite end of the slide, the spring enlargement or bulge being formed in the tubular portion. Short pins 15, having heads 16, are inserted and secured `in the ends of the tubular portions of these slides.

It will be obvious that there are many ways in which my invention may be carried into effect without limitation to the exact details disclosed. Hence I do not wish to be limited to the details shown.

In operation the stud in its normal condition, as shown in Fig. 1, is inserted in the eyelet or buttonhole, using the pointed end when inserted, so head 1 rests against thefront of bosom. Then the pointed end is grasped and sliding tube pulled down until the outer or upper end is incased in hollow tube, when the post 2 will enter eyelet. Then sliding tube 5 is pushed upward until the bulb 8 engages the aperture 4, and thus holds it securely in position.

By means of my construction the Cross-bar may be of equal length on opposite sides of the post, thus preventing.;r the stud from Withdrawal from either an eyelet or butto'nhole.

Having thus described my invention, what I claim is- A stud or button having a tubular post provided with an angular bend forming a tubular guideway for a sliding shoe, an aperture formed in the outer Wall of the bend, a tubular sliding shoe fitted into the tubular guide- Way, said shoe having a headed pin in one end thereof and a central enlarged spring p0rtion which engages the aperture in the outer wall of the post to hold the shoe extended at right angles to the post, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
